It can’t be interpreted as support, because deciding to stay so you can campaign and vote to turn Texas blue is commendable.
I don't have any insight into how many Salesforce employees will take up this offer, and I think that proportion will impact how those that stay will be perceived. All I know for sure right now is I'm glad I don't live in Texas, so I don't have to make this decision for myself.
This is providing assistance for people who want to leave, but says nothing at all about people who don’t want to.
